Ultraviolet-Visible (UV-Vis) spectrum was investigated by using a hybrid method which combines CIS-DFT (B3LYP). The absorption bands are assigned to n->π* transitions. The results were showed 4-(phenylthio) phthalonitrile used in Dye Sensitized Solar Cells [DSSC] give a good conversion efficiency. 收起
